Biological control of thrips and whitefly on strawberries withAmblydromalus limonicus and Amblyseius swirskii


Abstract: The performance of the predatory mite Amblydromalus limonicus was compared toAmblyseius swirskii in the control of thrips (Frankliniella occidentalis) and whiteflies(Trialeurodes vaporariorum) on greenhouse-grown strawberries. In addition, it was investigatedif the provision of pollen as supplementary food improves the performance of A. limonicus. Bothpredatory mite species significantly reduced whitefly and thrips densities compared to theuntreated control. Whitefly control was significantly better with A. limonicus than withA. swirskii whereas the differences in thrips control where less pronounced. The addition ofpollen had a positive effect on the A. limonicus population but did not improve pest control.
